Global Research on Hereditary Hearing Impairment Over the Last 40 Years: A Bibliometric Study

Research on hereditary hearing impairment has had several boosts to identify deafness-causing genes. The number of studies regarding the diagnosis and treatment modalities of hereditary hearing impairment is enormous and increasing; however, little or no research has been conducted for evaluating the development of scientific output and trends in the field. Here, we provide a comprehensive overview of centers that focus their research on hereditary hearing impairment and their scientific output.

Bibliometric analysis of the publications related to hereditary hearing impairment published between 1980 and 2019 were used in this study, which were also indexed in Web of Science database.

The highest number of scientific articles on hereditary hearing impairment came from the United States, and it was also the most cited country. The University of Iowa is a leading center in the domain of hereditary hearing impairment in the world over the last 40 years. Fudan University, Central South University, and Harvard Medical School are also institutions that have had a focus on hereditary hearing impairment.

There is a progressive increase in scientific papers on hereditary hearing impairment over the last 40 years that we have found in our bibliometric study. We identified key centers in the scientific research on hereditary hearing impairment in the world and also key journals that focus on hereditary hearing impairment. This information can facilitate new researchers in this field to seek collaboration with experienced partners, better synthesize the orientation and boundaries of the subject, and find target journals. Ultimately, we provided a certain benchmark value for key centers that perhaps should have a more prominent role in constructing experimental research or even clinical guidelines.
